## Facts

- Sell SKUs **LM-VERSATILE/1500|2000|3000** and **LM-RUSTOFF/1500|2000|3000** (suffix = fibre wattage).
- Both use dual-galvo 2D beam movement, a cutting-grade CW source, **20 m fibre cord**, and a similar touchscreen.
- Pulse markers (LF-20/30/50) are a different class from CW weld/clean/cut sources (LF-1000 and up). Welding-grade CW is less stable, lower frequency, fibre usually under 10 m. Cutting-grade is more stable, higher frequency, 20 m or longer.
- New units are barebone plus separate source: allow **one day** to assemble, set, and test after an order.
- **Versatile**: one torch, tip-swap for weld, cut, general clean, and weld-seam clean.
- **RustOff**: one torch, larger lens (more than double area), cleaning-only; **new RustOff cannot cut**. Cleaning speed more than double Versatile.
- When Versatile cuts: clean lens, correct focus lens, nozzle at focus, compressed air.
- Older 7 m-lead models remain usable and cheaper while stock lasts; prefer the 20 m SKUs for new quotes.
